Wraithlord with starcannon=120 points
3 warwalkers with shurican cannons 18 str 6,shots a turn=120 points
Uber freaks go for the warwalkers from what I've seen.
multiple lone vypers with starcannons and shurican cannon(like tornados slightly more vulnerable)
Until 5th ed (when they stop being able to shoot quite so many weapons (so don't buy them)but become
slightly more resilient given the nature of the damage table) even though they lose smf rule.. falcons (with everything but the turbo booster.) for
VP denial good shooting base and psychology (of most hated unit by unwashed masses including myself
)
Wraithlords are still ok,but the price bumps made them a tad cumbersome, in 5th ed with them running into combat they'll start appearing again.
banshees and harlies are always good (if only for hammer and anvil smashing)
Eldrad...
In most big armies comp folks seem to just take 2x3 jetbikes and then take all the lush stuff from the rest of the codex.. but gaurdian hordes can be funny, and pathfinders are brutal (god damn Mr 6 sitting in 4+ (becomes 2+) terrain sniping at me forever and ever and ever)
Have a look at a few template eldar lists and then merge them together to give it your brothers personal touch.
hope something their sounds useful
